Harwil manufacturers flow and level switches, temperature sensors and pump controllers in the USA. Our CF-112 chemical feed pump controller is the industry standard. This unique controller is low cost, simple to install and ultra-reliable. We are introducing four new pump controllers for all of your chemical feed and level control requirements. Our new L-21 lever switch offers 1 inch to 36 inch differentials without using an expensive latching controller. Ellis Anderson - Sales Director.
